JAMB SPRING-HINGE.

To all whom it may concern: I l

Be it known that I, OSCAR KATZENBERGER, a citizen of the United States,and a resident of Chicago, inthe county of Cook and State of Illinois,have invented a new and Improved Jamb Spring-Hinge, of which thefollowing is a full, clear, and exactdescription.

This invention relates to spring hinges and has for an objecttheprovision of an improved construction of jamb hinge that may be usedone. jamb 'of any width without the use of a hanging strip orwithoutmortising the jamb.

. Another object in viewisto provide a V jamb hinge designed to becountersunl'c only in thedoor. I i p A still further object in view, isto provide a j amb hinge with a pair of drums and a connecting plateformed to resist the strain in such manner that the strain will bedistributed throughout the plate.

In the accompanying drawing Figure 1 is a sectional view through Fig. 3on line 1-1.

Fig. 2 is a face view of the door jamb with the-door and hinge moved toone side.

Fig. 3 is a transverse horizontal section through Fig. 1 on line 33.

Fig. 4 is a sectional view on line 4-4. p p t Fig. 5 is a sectional viewthrough Fig. 2 on line 5- -5.

Fig. 6 is a front view of the drums and connecting plate, together witha reinforcing member associatedtherewithh through Fig. 3

Referring to the accompanying drawings 5;

by numerals, 1 indicates a door jamb to which the door 2 is pivotallyconnected by one or more hinges. In arranging the hinge in position itwill be noted that the jamb 1 is not in any way countersunk or cut asmdicated by Fig. 4 while the door is cut to an appreciable extent foraccommodating certain parts of the hinge. As shown in Figs. 3 and 6 thehinge is provided with a body 3 which is formed from a plate bent so asto produce the barrels 4 and 5 and overlapping leaves 6 and 7. Theleaves 7 are formed so that their edges will be at an angle, as shown inFig. 6, said angle being diagonal from top to bottom of the body 3whereby a plurality of fastening rivets 8 may be used for forming arigid body and for causing the strain to be distributed throughout thebody on both of the leaves Specification of Letters Patent.

instead of centrally of the body on one leaf, which would be the case ifthe meeting edges of theparts of leaf 7, were in the center. In thedrawing a double-acting hinge has been shown for the purpose of straightin Fig. 6 merely'for the purpose of A leaf 14 is provided. and

retaining screws l5, the turned-up ends 17 and 18 fitting the top andbottom of the notched-out section 19 in door 2. The leaf 14 is providedwith end'members 16 and 20 and also with a bracing wall 21 against whichthe pin 22 rests when the hingeis in operation. A pintle 23 extendsthrough the ends 16 and 20 and also through the barrel 4 so as to holdthe parts in proper position. A spring 24 is arranged in barrel 4'withone end connected to the. endo16in any suitable manner and the oppositeend to a winding disk 25, which winding. disk is formed with a pluralityof apertures 26 for accommodating the lugor pin 22, whereby the springmay be wound to any desired; eX- tent.

1 Barrel- 5 is provided with .a ,leaf27, which leaf is fitted on to thebarrel 5 in a similar manner to the way leaf 14 is fitted on to barrel4, the leaf being associated with a spring pintle and other partssimilar to barrel 5 and will therefore need no additional description,leaf 27 being connected to the jamb 1 while leaf 14 is connected to thedoor 2. It will be noted that in forming the body 3 and the barrels 4and 5, the barrels are arranged on one side, or, rather, on one face ofthe body 3, whereby the leaf 27 may properly fit fiatwise against thedoor frame or jamb 1. In fact, the hinge could be placed against a walland properly secured inposition and support a door designed to swing inboth directions or one direction, as all the swinging movement is donefrom the center of the respective barrels. In producing this result theleaf 14 is formed of the turned-up members 17 and particularly in Fig.4. QEIld 13 is shown 18 whereby a socket is provided which re ceives thecentral part or body 6 and also part of the leaf 27. Itwillbe noted thatthe central leaf section formed of barrels 4L and 5 and the body 6 isconstructed of one piece of material and the body 6 is reinforcedloyhconsequently, being placed accurately. By

arranging the parts as shown in the drawing and as described above, nohanging-strip is necessary, and, consequently, no 'inortising of thejamb as all of the mortising is done in the door. This result isattained, as shown in the drawing, by forming the bar rels on the edgesof the body and one face thereof, which leaves suiiicient space betweenthe barrels and the jamb to avoid frictional engagement whether thehinge is a single or doubleacting jamb hinge. One of the objects inproducing a hinge which will not need a hanging strip mortised into thejamb is that saidstrip must be accurately positioned or the door willnot hang properly, while by providing a hinge which' is mortised intothedoor only and secured to the jamb at any point the door may be hungaccurately without any appreciable trouble.

'VVhat I claim is: i i

1. A jainb hingev comprising a pair of barrels and a body formed of onepiece bent so as to produce the two barrels on the edges of the body andon one face thereof and'to produce a body having a solid section and adivided section, said divided section being arranged with a divisionline diagonally across the body whereby vertical strain will bedistributed to all parts of the body, means for rigidly connecting saidsections together, a pair of leaves, means for resiliently connectingone of said leaves with one of" said barrels, and means for resilientlyconnecting the other of said leaves with the other barrel.

2. In a double swinging or three-leaf hinge, a central leaf sectionformed from .asingle sheet of metal bent for producing a pair of barrelsat each edge, a central solid body portion and a pair of body endmembers arranged with their meeting edges at a diagonal whereby thevertical strain will be taken up by all of the body porti'ons and meansfor-clamping all o'f said body portions rigidly together.

3. In a hinge of the character described,

a central leaf section formed with a pair of barrels, a body portionformed from a plurality of plate"po'rtions mergingdnto said barrels, oneof the plate portions having diagonal meeting edges, reinforcing face oftheir connecting section and'spaced L outwardly from the jamb when inuseyn one of said barrels-"being pivotally mounted onv said firstmentioned leaf and the second mentioned leaf being pivotally mounted onthe other barrel, said last mentioneddeaf and the connecting sectionbetween said barrels fitting within the turned-up ends of the firstmentioned'leaf. I T" oscan ara-nu sances.
